Answer:

#s = 4.5#

Explanation:

Step 1) Expand the terms in parenthesis.
Step 2) Combine like terms
Step 3) Solve for #s# while keeping the equation balanced

#3s + 10s - 2 = 56.50#

#(3 + 10)s - 2 = 56.50#

#13s - 2 = 56.50#

#13s - 2 + 2 = 56.50 + 2#

#13s = 58.50#

#(13s)/13 = 58.50/13#

#s = 4.5#
